' COMBINED RGAD DRAG AND SCARIFIER.

Application filed November 24, 1925. Serial No. 71,188.

My invention relates to improvements in combined road drag and scarilier, and it consists in the combinations, constructions and arrangements herein described and claimed.

An object of my invention is to provide a simple but efficient device by means of which roads may be surfaced, leveled and maintained at a minimum cost.

A further object of my invention is to {provide a device of the type described, which is made entirely of metal, and which is adjustable so as to permit it to be used as a drag or as a scarifier and leveler.

A further object of the invention is to provide a device which can be manufactured at a relatively low cost, but which is so constructed that there is little or no danger of injury when obstructions, such as a large stone, are encountered.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming part of this application, in which Figure 1 is a plan View. of the device,

Figure 2 is a side view of the device shown in Figure 1, and

Figure 8 is a detailed perspective view of a portion of the device.

In carrying out my invention, I provide afront blade or scraper member 4 which has a fiat face. A rear blade 5 of similar construction is also provided. These blades, as will be seen from Figure 1, extend from side to side of the machine. The front blade has riveted thereto a bracket 0, while a similar bracket 7 is riveted to the rear of the rear blade. These brackets are in the shape of angle irons, as shown.

Connecting the front and rear blades are longitudinal frame members 8. These frame members, as will be observed, are preferably made of angle irons, which are bent upwardly at their forward ends, and then downwardly at their rear ends, and are secured to lugs 9 and 10 which are carried by the brackets 6 and 7 respectively. Mounted on the frame members 8 is a floor board 11.

' Secured to the front blade 4 is a shoe 12 which is bent rearwardly and upwardly, and which is provided with a row of teeth 13 and a second row of teeth 14, the teeth of the latter row being staggered with respect to the teeth of the row 13. Art the front and at the rear are looking segments 15 and 16 respectively. Levers 17 and 18 are provided for manipulating the blades 4 and 5. The construction is such that the blades 4 and 5 arepivotally secured at 19 and 20 respectively to the frame members.

Carried by the front bracket are draft bars 21, which are connected by chains 22 to a central draft chain 23.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. When it is desired to use the drag as a leveler or to scrape off the higher places of the road, the levers are set as shown in Figure 2, and are held by the locking members 24, so that when the device is drawn along, theblades act as scrapers to level off the uneven portions of the road.

When it is desired to use the device as a scarifier or to harrow the road, the lever 17 is pulled rearwardly, thereby bringing the teeth 13 and 14 into the position shown in Figure 3, in which position the blade 4 clears the road. In this position the teeth will dig into the road, thus tending to break it up, while the rear blade 5 will tend to level off the broken-up portions. Both blades 4 and 5, of course, can be set at different angles by means of their respective levers, so as to act as scrapers or as drags to smooth out the dirt or gravel.

One particular feature to which I desire to call attention is the fact that the shoe 12 is rounded so as to permit the rocking of the scarifier attachment into or out of position with the least resistance, and at the same time causes the front blade to clear the ground when the teeth are put into servlce.

I claim:

1. A combined road drag and scarifier comprising a frame, a pair of adjustable scraper blades carried by said frame, a tootl bearing member secured to one of said blades, and means for simultaneously moving said last named blade to bring said teeth into operative relation with the ground, and for bringing said tooth-bearing blade out of operative relation with the ground.

2. A combined road drag and scarifiel comprising a frame, a front scraper blade carried by said frame, a tooth-bearing shoe secured to said blade, 2. rear scraper blade carried by said frame, and means for moving said front blade to bring it out of operative relation with the ground and to bring said teeth into operative relation with the ground.

3. A combined road drag and soarifier comprising a frame, a scraper blade pivotally connected at the front of said frame, a scraper blade carried at the rear of the frame, a shoe secured to said front blade, teeth carried by said shoe, means for swinging said front blade about its pivotal mounting to bring the teeth into operative relation with the ground and the blade out of operative relation with the ground, and means For holding said blade and said tootlr bearing shoe in either of their shifted positions.

it. A combined road drag and s-arifier comprising a frame, a scraper blade pivotall mounted at the front of the frame, a shoe secured to the rear face of said blade and being bent rearwardly and upwardly, teeth carried by the shoe and normally out ot' operative lelation with the ground when the blade is in a Vertical position, means for pivotally mounting the blade and the $1100 on said frame, means for shifting the blade and the shoe on their pivotal mounting, means for locking the shifting means, and a blade carried at the rear of the frame, said last named blade being parallel with said first named blade.

5. A combined road drag and scarifier comprising a frame, a scraper blade pivotally mounted at the front or the frame, a shoe secured to the rear face of said blade and being bent rearwardly and upwardly, teeth carried by the shoe and normally out; of operative relation with the ground when the blade is in a vertical position, means for pivotally mounting the blade and the shoe on said frame, means for shitting the blade and the shoe on their pivotal mounting, means for locking the shifting means, a blade pivotally mounted at the rear of the frame, said last named blade being parallel with said first named blade, and means for shifting said rear blade to adjustits angular position with respect to the ground.
